摘要： A molded case circuit breaker having an operating mechanism including a collapsible toggle linkage, an operating handle and a movable frame. The collapsible toggle linkage includes a rectangular cross section knee pin non-rotatably held within an open rectangular slot in an upper link of the linkage. The operating handle pivots about a first pivot point when moving between ON, OFF and TRIPPED positions. The operating handle pivots about a second pivot point when moving to a RESET position thereby reducing the lateral force component of the operating springs of the operating mechanism for reliable return of the handle to the OFF position. Also, bifurcated movable contact fingers are provided for pivotal movement about a fixed pin to break contact welds and a trapezoidal cross section shaft interconnects the movable contact fingers.

摘要： A flat plastic retainer having a loop at one end rotatably receiving a threaded fastener and a tongue and outboard fingers unidirectionally extending from the loop to engage an essentially upright leg of a terminal of a circuit breaker, has lateral projections on the tongue which are compressed when the tongue is inserted through an opening in the leg of the terminal and expand when the projections pass beyond the opposite side of the terminal to resist pull-out of the retainer from the terminal. The outboard fingers are deflected along the terminal to bias the fastener into engagement with an associated leg of the terminal having an opening through which one portion of a threaded fastener pair projects to engage the other portion.

摘要： A subframe is coaxially pivotally mounted with a movable frame of the operating mechanism of a molded case circuit breaker and is locked to the frame by a bell crank pawl which is pivotally mounted on the subframe. A leaf spring assembly rigidly attached to the subframe overlies the movable contact finger to engage the same in the circuit ON condition of the circuit breaker to provide desired contact force. The bell crank pawl is released upon an incrementally small amount of initial movement of the movable contact arm in response to blow-open magnetic repulsion forces to release the movable contact finger for pivotal opening movement relative to the movable frame of the circuit breaker operating mechanism.

摘要： In a molded case circuit breaker with an interchangeable thermalmagnetic trip unit, the C-shaped heater transformer core is permanently held in place in the casing by a load bus strap with the gap in the core facing the trip unit. When the interchangeable trip unit is inserted into the molded casing, a magnetically permeable member mounted in the trip unit is aligned in the gap in the heater transformer core. The bimetal of the trip unit is fixed at one end to an electrically conductive sleeve surrounding the magnetically permeable member and forming the secondary of the heater transformer. The length of the magnetically permeable member is selected to establish the current conditions at which the bimetal trips the circuit breaker. The bus strap has an off-set section forming a first shoulder against which one wall of the housing of the interchangeable trip unit seats, and a second shoulder against which a pole piece backed by the heater transformer core seats to fix a gap between the pole piece and the armature in the interchangeable trip unit providing the instantaneous magnetic trip function.
